Pendleton, OR -

The husband of a woman found beaten along a trail in Pendleton says she will have a lot of relearning to do once she's out of an induced coma.

Dan Lange tells the East Oregonian that his wife, Karen, faces many uncertainties. For instance, her doctors don't know whether she will be able to sing.

She leads her church music program, sings at the Pendleton Round-Up, and is a member of the local symphony and chorale.

Dan Lange says Karen has briefly opened both eyes, and her left eye is open often.

An attacker beat her on Aug. 9 with a length of pipe.

Investigators say a transient is a person of interest. They say DNA from the attack is linked to a killing last year.
